Quartz tube is a special industrial technology glass made of silica, which has a series of excellent technical characteristics.

I.Physical properties

High temperature resistance: The quartz tube can withstand high temperatures of around 1250 ° C, and its softening point temperature is about 1730 ° C. It can be used for a long time at 1100 ° C, and the maximum operating temperature for a short time can reach 1450 ° C.

Good thermal stability: quartz glass has a very small coefficient of thermal expansion and can withstand severe temperature changes. If quartz glass is heated to around 1100 ° C, it will not burst when placed in room temperature water.

Good light transmittance: Quartz glass has good light transmittance in the entire spectral band from ultraviolet to infrared, with a visible light transmittance of over 93%, especially in the ultraviolet region, with a maximum transmittance of over 80%.

II. Chemical properties

Corrosion resistance: Except for hydrofluoric acid, quartz glass hardly reacts chemically with other acids, and its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Its chemical stability at high temperatures is unmatched by other engineering materials.

Excellent electrical insulation: The resistance value of quartz glass is equivalent to ten thousand times that of ordinary glass, making it an excellent electrical insulating material, even at high temperatures.

III. Application field

Quartz tubes are widely used in many fields due to their excellent physical and chemical properties.

Electric light source: such as electric fire, electric oven, electric heater and other heating equipment.

Semiconductor: used for diffusion, alloy preparation, etc., to ensure product quality.

Optical communication: Take advantage of its excellent light transmission properties.

In addition, quartz pipes are also used in military, metallurgy, building materials, chemistry, machinery, electricity, environmental protection, and other fields.

IV. Other characteristics

Variety: Quartz tubes can be roughly divided into transparent quartz tubes (outer diameter 1.5mm to 300mm), UV filter quartz tubes, and colored quartz tubes.

Fragile: Although quartz tubes have a variety of excellent properties, they are fragile and require attention to avoid bumping during use.

Quartz tubes have a variety of excellent technical characteristics, which make them widely used in many fields.
